This looks like a GPU driver related issue. If you have some other hardware (PC) with a different (modern) GPU available, please test the procedure there first.

Hi Triplus, at home i do not have another more modern computer. I am trying to run this on a Acer 5750G with a Geforce GT540M with CUDA 1Gb of ram. I have reinstalled the geforce drivers today to ensure it wasnt a driver issue.

Hi Triplus, the error was due to the integrated Intel GPU, however although paraview doesnt have the open gl es errors it also does not display anything. It seems to be an issue with Paraview/my laptop and not freecad or the work bench.

There is a big chance your laptop has 2 GPUs. And the above error is related to using the Intel one. AFAIK on Windows user has some settings and can assign desired GPU to a specific program, as FreeCAD, try to to that.

I have just installed the cfdof module in freecad to start some trials and I have come up with 1 semi major issue and 1 major issue.
1st) when I create a volume (a rectangular section which is 40mmx40mmx2500mm) in part design and create the container for open foam and try to mesh the volume using cfmesh I get the below error.

Thanks for confirming.

As now you don't get any additional errors and still don't see any results on the screen. That likely is becoming a question for somebody proficient in using the mentioned workbench. Best to follow advice by @oliveroxtoby.
